Re: Might be good for movie distro
The human eye typically can receive about 10B triangles in stereo (that is how we form depth), so to do 3D it will take about 8kx4k at 8 feet to make it seamless--however compression artifacts can cause some unusual side effects. That is why IMAX is going to dual laser projectors (4k) which would pretty much be good enough, although not imperceptible. Laser projectors will ultimately solve the problem over time. That and some are going to 48 FPS for motion issues.
8K would probably be broadcast quality, and then from there they would hack it up with compression for home consumption where as people have said visual artifacts can crop up, maybe to 4k in ten years or so.
3D will be the kicker over time, and this will need new advanced algorithms to keep the bitrates reasonable.
All of this is going to take big pipes, and that means fibre is in....
I don't know if it is Cox or if it is the network but sometimes, particularly for sports, CBS HD is so over-compressed it is annoying to watch. It's like the image is made of Legos. But I see the same with some OTA HD...like networks want to punish you with degraded picture to drive you to cable or DBS where they get rebroadcast fees.
